Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for annealing ultra-thin carbon steel strips, and in particular to a pretreatment device based on the annealing of ultra-thin carbon steel strips. Background Technology

[0002] Ultra-thin carbon steel strip is a type of carbon steel strip with an extremely small thickness (typically between 0.05mm and 0.10mm). It possesses high precision, high strength, and excellent machinability, and is widely used in electronics, precision instruments, automobiles, and new energy fields. To eliminate work hardening, optimize the microstructure, improve material properties, and meet specific requirements for subsequent processing or use, annealing is necessary for ultra-thin carbon steel strip. However, the surface of ultra-thin carbon steel strip is easily contaminated with oil, and edge waviness or warping can occur, affecting the quality and efficiency of the annealing process. Therefore, we urgently need a pretreatment device for ultra-thin carbon steel strip annealing to improve the quality and efficiency of the annealing process.

[0003] Currently, the pretreatment for annealing ultra-thin carbon steel strip includes:

[0004] 1. Degreasing treatment, used to remove oil stains from the surface of extremely thin carbon steel strips;

[0005] 2. Flattening treatment, used to flatten the wavy or warped edges of the ultra-thin carbon steel strip surface to ensure that the surface of the ultra-thin carbon steel strip remains flat;

[0006] Currently, the pre-treatment for degreasing and pre-flattening of ultra-thin carbon steel strips before annealing are performed separately. This requires transferring the degreased ultra-thin carbon steel strip to the flattening stage or vice versa. The pre-treatment steps are cumbersome and affect the efficiency of the pre-annealing process. Furthermore, the mutual handling can damage the ultra-thin carbon steel strip and affect the quality of the pre-annealing process. Utility Model Content

[0007] To address the shortcomings of existing production technologies, the applicant provides a pretreatment device based on the annealing of ultra-thin carbon steel strips. By improving the structure of the pretreatment device, the degreasing and flattening processes are integrated into a single unit, thereby improving the processing efficiency and quality of the pretreatment for ultra-thin carbon steel strip annealing.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A pretreatment device for annealing ultra-thin carbon steel strip is provided. The pretreatment device is located between the unwinding section and the annealing section of the ultra-thin carbon steel strip. It includes an oil removal mechanism and a flattening mechanism arranged sequentially along the conveying direction of the ultra-thin carbon steel strip. The oil removal mechanism is used for pre-treatment of the ultra-thin carbon steel strip to remove oil stains from the surface of the ultra-thin carbon steel strip. The flattening mechanism is used for pre-treatment of the ultra-thin carbon steel strip to eliminate edge waviness or warping of the ultra-thin carbon steel strip, so as to keep the shape of the ultra-thin carbon steel strip flat. After being unwound, the ultra-thin carbon steel strip undergoes oil removal and flattening treatment in sequence, and then enters the annealing section for annealing treatment.

[0010] Therefore, by integrating the degreasing and flattening mechanisms of the ultra-thin carbon steel strip pre-annealing treatment into a single device, the ultra-thin carbon steel strip can undergo both degreasing and flattening treatments simultaneously before annealing. Compared to the existing separate degreasing and flattening treatment methods for ultra-thin carbon steel strips, this method is simpler in structure and easier to operate. Since the pre-treatment is performed on a single device, there is no need to repeatedly handle the ultra-thin carbon steel strip. On the one hand, this simplifies the pre-annealing treatment steps, thereby improving the processing efficiency. On the other hand, it avoids damage to the ultra-thin carbon steel strip caused by repeated handling, thus improving the processing quality. Furthermore, the method of performing degreasing treatment first and then flattening treatment can prevent continuous oil contamination during the transport of the ultra-thin carbon steel strip, thereby further improving the degreasing efficiency and quality.

[0011] As a further improvement to the above technical solution: the degreasing mechanism includes an upper degreasing section and a lower degreasing section. The upper degreasing section is located above the lower degreasing section and connected to the lower degreasing section. The ultra-thin carbon steel strip is located between the upper degreasing section and the lower degreasing section. The upper degreasing section is used for degreasing the upper surface of the ultra-thin carbon steel strip, and the lower degreasing section is used for degreasing the lower surface of the ultra-thin carbon steel strip.

[0012] As a further improvement to the above technical solution: the degreasing mechanism further includes: a plurality of first driving members, the first driving members being located between the upper degreasing section and the lower degreasing section, and the first driving members being connected to the lower degreasing section. The telescopic end of the first driving member is connected to the upper degreasing section, and the first driving member is used to adjust the distance between the upper degreasing section and the lower degreasing section. Thus, the distance between the upper and lower degreasing sections can be adjusted by the first driving members. During degreasing, the upper and lower degreasing sections move relative to each other, causing the first felt and the second felt to contact the upper and lower surfaces of the ultra-thin carbon steel strip respectively, so that the alcohol on the first and second felts removes oil stains from the upper and lower surfaces of the ultra-thin carbon steel strip. After degreasing, the upper and lower degreasing sections move towards each other, causing the first felt and the second felt to move away from each other. A large space exists between the first felt and the second felt for workers to disassemble and replace the oil-stained first and second felts.

[0013] As a further improvement to the above technical solution: the upper degreasing section includes: a first liquid storage tank, a first oil spray hole, and a first felt. The first liquid storage tank is used to store alcohol. A plurality of first oil spray holes are opened on the side of the first liquid storage tank near the lower degreasing section. The first felt is located on the side of the first liquid storage tank near the lower degreasing section, and the first felt is connected to the first liquid storage tank by a first Velcro and a second Velcro. The alcohol stored in the first liquid storage tank drips onto the first felt through the first oil spray hole under the action of gravity, and acts on the upper surface of the ultra-thin carbon steel strip through the first felt to perform degreasing treatment on the upper surface of the ultra-thin carbon steel strip.

[0014] As a further improvement to the above technical solution: the lower degreasing section includes: a second liquid storage tank, a second oil spray hole, and a second felt. The second liquid storage tank is used to store alcohol. Multiple second oil spray holes are opened on the side of the second liquid storage tank near the upper degreasing section. The second felt is located on the side of the second liquid storage tank near the upper degreasing section, and the second felt is connected to the second liquid storage tank by a third hook and loop fastener and a fourth hook and loop fastener. A compressor is installed inside the second liquid storage tank. The alcohol stored in the second liquid storage tank is sprayed onto the second felt through the second oil spray hole under the action of the compressor, and then acts on the lower surface of the ultra-thin carbon steel strip through the second felt to degrease the upper surface of the ultra-thin carbon steel strip.

[0015] As a further improvement to the above technical solution: the flattening mechanism includes an upper flattening part and a lower flattening part, the upper flattening part being located above the lower flattening part, and the upper flattening part and the lower flattening part being used together for the flattening process of ultra-thin carbon steel strips.

[0016] As a further improvement to the above technical solution: the flattening mechanism further includes: a plurality of support rods, the support rods being located between the upper flattening part and the lower flattening part, and the upper flattening part and the lower flattening part being connected through the support rods.

[0017] As a further improvement to the above technical solution: the upper flattening section has the same structure as the lower flattening section; the upper flattening section includes: a support block, multiple flattening rollers, a gear belt assembly, and a second driving component. The multiple flattening rollers are distributed at equal intervals along the conveying direction of the ultra-thin carbon steel strip. The flattening rollers are rotatably connected to the support block. The gear belt assembly is embedded within the support block. The second driving component is installed outside the support block. The driving end of the second driving component is connected to the input end of the gear belt assembly, and the output end of the gear belt assembly is connected to the flattening rollers. Thus, activating the second driving component drives the gear belt assembly to rotate, causing the multiple flattening rollers to rotate around their own axes. In this way, the rotating flattening rollers of the upper and lower flattening sections work together to flatten the ultra-thin carbon steel strip, ensuring that the surface of the ultra-thin carbon steel strip remains flat and free from edge waviness or warping.

[0018] As a further improvement to the above technical solution: the width d1 of the flattening roller is equal to the width d2 of the ultra-thin carbon steel strip; d1 > d2. Therefore, by using the design that d1 > d2, it is ensured that the surface of the ultra-thin carbon steel strip is completely pressed onto the flattening roller, thus ensuring that the entire ultra-thin carbon steel strip is completely flattened and that no under-pressing occurs.

[0019] As a further improvement to the above technical solution, it also includes: a base, on which the degreasing mechanism and the flattening mechanism are both mounted.

[0020] The beneficial effects of this utility model are as follows:

[0021] By integrating the degreasing and flattening mechanisms of ultra-thin carbon steel strip pre-annealing treatment into a single device, the ultra-thin carbon steel strip can undergo both degreasing and flattening treatments simultaneously before annealing. Compared to existing methods that separate degreasing and flattening processes, this method is simpler in structure and easier to operate. Since the pre-treatment is performed on a single device, there is no need to repeatedly handle the ultra-thin carbon steel strip. This simplifies the pre-annealing process, improving efficiency, and avoids damage to the strip caused by repeated handling, thus enhancing the quality of the pre-annealing treatment. Furthermore, the method of performing degreasing before flattening prevents continuous oil contamination during transport, further improving both degreasing efficiency and quality.

[0022] This utility model also has the following advantages:

[0023] 1. This utility model allows for adjustment of the distance between the upper and lower degreasing parts via a first driving component. During degreasing, the upper and lower degreasing parts move relative to each other, causing the first and second felts to contact the upper and lower surfaces of the ultra-thin carbon steel strip, respectively. The alcohol on the first and second felts removes oil stains from the upper and lower surfaces of the ultra-thin carbon steel strip. After degreasing, the upper and lower degreasing parts move towards each other, causing the first and second felts to move away from each other. There is a large space between the first and second felts for workers to disassemble and replace the first and second felts that are contaminated with oil.

[0024] 2. This utility model uses a design method where d1 > d2 to ensure that the surface of the ultra-thin carbon steel strip is completely pressed onto the flattening roller, thus ensuring that the entire ultra-thin carbon steel strip is completely flattened and there is no leakage of pressure.

[0039] 3. Base. Detailed Implementation

[0040] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0041] like Figures 1 to 10The diagram shows the preferred embodiment of this utility model. This embodiment is a pretreatment device for annealing ultra-thin carbon steel strip. The pretreatment device is located between the unwinding section and the annealing section of the ultra-thin carbon steel strip. It includes an oil removal mechanism 1 and a flattening mechanism 2 arranged sequentially along the conveying direction of the ultra-thin carbon steel strip. The oil removal mechanism 1 is used for the oil removal pretreatment of the ultra-thin carbon steel strip to remove oil stains from the surface of the ultra-thin carbon steel strip. The flattening mechanism 2 is used for the flattening pretreatment of the ultra-thin carbon steel strip to eliminate edge waviness or warping of the ultra-thin carbon steel strip, so that the ultra-thin carbon steel strip maintains a flat shape (i.e., has high flatness). After being unwound, the ultra-thin carbon steel strip undergoes oil removal treatment and flattening treatment in sequence, and then enters the annealing section for annealing treatment. Therefore, by integrating the degreasing mechanism 1 and the flattening mechanism 2 of the ultra-thin carbon steel strip pre-annealing treatment into a single device, the ultra-thin carbon steel strip can be simultaneously degreased and flattened before annealing using a single set of equipment. Compared to the existing method of handling degreasing and flattening of ultra-thin carbon steel strips separately, this method is simpler in structure and easier to operate. Since the pre-treatment is performed on a single device, there is no need to repeatedly handle the ultra-thin carbon steel strip. On the one hand, this simplifies the pre-annealing treatment steps of the ultra-thin carbon steel strip, thereby improving the processing efficiency. On the other hand, it avoids damage to the ultra-thin carbon steel strip caused by repeated handling, thus improving the processing quality of the ultra-thin carbon steel strip pre-annealing treatment. In addition, the method of performing degreasing (e.g., rolling oil) treatment first and then flattening treatment can avoid continuous oil contamination during the transport of the ultra-thin carbon steel strip, thereby further improving the degreasing efficiency and quality of the ultra-thin carbon steel strip.

[0042] In other words, since the ultra-thin carbon steel belt is continuously transported, if the oil on its surface is not removed in time, it will continue to be contaminated with other stains during the continuous transport process due to the oil contamination. This is to increase the efficiency and quality of oil removal of the ultra-thin carbon steel belt (because the oil contamination on the ultra-thin carbon steel belt increases).

[0043] In this embodiment, the degreasing mechanism 1 includes an upper degreasing section 101, a lower degreasing section 102, and a plurality of first driving members 103. The upper degreasing section 101 is located above and connected to the lower degreasing section 102. The ultra-thin carbon steel strip is located between the upper degreasing section 101 and the lower degreasing section 102. The upper degreasing section 101 is used for degreasing the upper surface of the ultra-thin carbon steel strip, and the lower degreasing section 102 is used for degreasing the lower surface of the ultra-thin carbon steel strip. The first driving members 103 are located between the upper degreasing section 101 and the lower degreasing section 102, and are connected to the lower degreasing section 102. The telescopic end of the first driving member 103 is connected to the upper degreasing section 101. The first driving member 103 is used to adjust the distance between the upper degreasing section 101 and the lower degreasing section 102. The upper degreasing section 101 includes: a first liquid storage tank 1011, a first oil spray hole 1012, and a first felt 1013. The first liquid storage tank 1011 is used to store alcohol. A plurality of first oil spray holes 1012 are opened on the side of the first liquid storage tank 1011 near the lower degreasing section 102. The first felt 1013 is located on the side of the first liquid storage tank 1011 near the lower degreasing section 102, and the first felt 1013 is connected by a first Velcro strap 1. 014. The second Velcro strap 1015 is connected to the first liquid storage tank 1011; the alcohol stored in the first liquid storage tank 1011 drips through the first oil spray hole 1012 onto the first felt 1013 under the action of gravity, and acts on the upper surface of the ultra-thin carbon steel strip through the first felt 1013 to degrease the upper surface of the ultra-thin carbon steel strip; the lower degreasing part 102 includes: a second liquid storage tank 1021, a second oil spray hole 1022 and a second felt 1023. The second liquid storage tank 1021 is used to store alcohol, and multiple first oil spray holes are opened on the side of the second liquid storage tank 1021 near the upper degreasing part 101. Two oil spray holes 1022 and a second felt 1023 are located on the side of the second liquid storage tank 1021 near the upper degreasing section 101. The second felt 1023 is connected to the second liquid storage tank 1021 by a third hook and loop fastener 1024 and a fourth hook and loop fastener 1025. A compressor (not shown in the figure) is installed inside the second liquid storage tank 1021. The alcohol stored in the second liquid storage tank 1021 is sprayed onto the second felt 1023 through the second oil spray holes 1022 under the action of the compressor. The alcohol is then applied to the lower surface of the ultra-thin carbon steel strip by the second felt 1023 to degrease the upper surface of the ultra-thin carbon steel strip.Therefore, the distance between the upper degreasing section 101 and the lower degreasing section 102 can be adjusted by the first driving member 103. During degreasing, the upper degreasing section 101 and the lower degreasing section 102 move relative to each other, so that the first felt 1013 and the second felt 1023 come into contact with the upper and lower surfaces of the ultra-thin carbon steel strip, respectively, so as to remove the oil stains on the upper and lower surfaces of the ultra-thin carbon steel strip by using the alcohol on the first felt 1013 and the second felt 1023. After degreasing is completed, the upper degreasing section 101 and the lower degreasing section 102 move towards each other, so that the first felt 1013 and the second felt 1023 move away from each other. There is a large space between the first felt 1013 and the second felt 1023 for workers to disassemble and replace the first felt 1013 and the second felt 1023 that are contaminated with oil.

[0044] In other words, compared with the existing method of cleaning and degreasing by spraying alkaline solutions, the alcohol method can reduce resource consumption and reduce wastewater generation. In addition, the first felt 1013 and the second felt 1023 can directly wipe away the oil stains adsorbed on the surface of the extremely thin carbon steel strip.

[0045] Specifically, the first Velcro 1014 and the second Velcro 1015 work together to enable the portable installation and removal of the first felt 1013 relative to the first liquid storage tank 1011; the third Velcro 1024 and the fourth Velcro 1025 work together to enable the portable installation and removal of the second felt 1023 relative to the second liquid storage tank 1021.

[0046] For example, the first driving component 103 is a cylinder.

[0047] In this embodiment, the flattening mechanism 2 includes: an upper flattening part 201, a lower flattening part 202, and a plurality of support rods 203. The upper flattening part 201 is located above the lower flattening part 202. The upper flattening part 201 and the lower flattening part 202 are used together for flattening the ultra-thin carbon steel strip. The support rods 203 are located between the upper flattening part 201 and the lower flattening part 202, and the upper flattening part 201 and the lower flattening part 202 are connected by the support rods 203. The upper flattening part 201 and the lower flattening part 202 have the same structure. The upper flattening part 201 includes: a support block 2011, a plurality of flattening rollers 2012, and a gear belt assembly. 2013 and the second driving component 2014, multiple flattening rollers 2012 are distributed at equal intervals along the conveying direction of the ultra-thin carbon steel strip, the flattening rollers 2012 are rotatably connected to the support block 2011, the gear belt assembly 2013 is embedded in the support block 2011, the second driving component 2014 is installed on the outside of the support block 2011, the driving end of the second driving component 2014 is connected to the input end of the gear belt assembly 2013, and the output end of the gear belt assembly 2013 is connected to the flattening rollers 2012; the width of the flattening rollers 2012 is d1, and the width of the ultra-thin carbon steel strip is d2; d1 > d2. Therefore, the second driving component 2014 is activated, which drives the belt gear set to move, so that multiple flattening rollers 2012 rotate around their own axis. In this way, the flattening rollers 2012 rotating in the upper flattening part 201 and the flattening rollers 2012 rotating in the lower flattening part 202 work together to flatten the ultra-thin carbon steel strip, ensuring that the surface of the ultra-thin carbon steel strip remains flat and that there are no wrinkles or curling edges. Through the design method of d1>d2, it is ensured that the surface of the ultra-thin carbon steel strip is completely acted on the flattening rollers 2012, thus ensuring that the entire ultra-thin carbon steel strip is completely flattened and there is no incomplete pressing.

[0048] Specifically, there are two gear belt assemblies 2013, located at both ends of the flattening roller 2012. Each gear belt assembly 2013 includes multiple gears and a belt. The gears are connected to the flattening roller 2012 and mesh with the belt. One gear (denoted as gear A) is connected to the flattening roller 2012 and the drive end of the second drive member 2014 at both ends. The second drive member 2014 drives gear A to rotate, thereby causing the flattening roller 2012 connected to gear A to rotate. At the same time, the rotation of gear A drives the belt to rotate, thereby causing the other gears to rotate, and thus causing each flattening roller 2012 to rotate around its axis.

[0049] For example, the second drive unit 2014 uses a motor.

[0050] In this embodiment, it also includes: a base 3, on which the oil removal mechanism 1 and the flattening mechanism 2 are both mounted. Specifically, the second liquid storage tank 1021 is connected to the base 3, and the lower flattening part 202 is connected to the base 3 through a support 204.

[0051] It should be noted that the transmission power of the ultra-thin carbon steel strip is maintained by the power generated by the unwinding of the anti-coiling section and the power generated by the rotation of the flattening roller 2012.

[0052] The pretreatment process for annealing the ultra-thin carbon steel strip of this utility model is as follows: First, the ultra-thin carbon steel strip is drawn out from the unwinding section and passes sequentially through the degreasing mechanism 1 and the flattening mechanism 2; then, in the degreasing mechanism 1, the upper and lower surfaces of the ultra-thin carbon steel strip are degreased by a first felt 1013 and a second felt 1023 soaked in alcohol (during this process, the first felt 1013 is in contact with the upper surface of the ultra-thin carbon steel strip, and the second felt 1023 is in contact with the lower surface of the ultra-thin carbon steel strip) to remove oil stains (e.g., rolling oil) from the upper and lower surfaces of the ultra-thin carbon steel strip; finally, in the flattening... Inside mechanism 2, the two flattening rollers 2012 of the upper flattening part 201 and the lower flattening part 202 work together to flatten the ultra-thin carbon steel strip, ensuring that the ultra-thin carbon steel strip always remains flat. After the ultra-thin carbon steel strip is pre-treated, the first driving member 103 increases the distance between the first felt 1013 and the second felt 1023, so that the first felt 1013 and the second felt 1023 can be disassembled for cleaning, ensuring that the first felt 1013 and the second felt 1023 remain clean, which facilitates the subsequent degreasing operation of the first felt 1013 and the second felt 1023.

[0053] In summary, this invention integrates the degreasing mechanism 1 and the flattening mechanism 2 of the ultra-thin carbon steel strip pre-annealing treatment into a single device. This allows for simultaneous degreasing and flattening of the ultra-thin carbon steel strip before annealing using a single set of equipment. Compared to existing methods that separate degreasing and flattening processes, this method is simpler in structure and easier to operate. Since the pre-treatment is integrated into a single device, there is no need for repeated handling of the ultra-thin carbon steel strip. This simplifies the pre-annealing process, improving efficiency, and avoids damage caused by repeated handling, thus improving the quality of the pre-annealing treatment. Furthermore, the method of performing degreasing first and then flattening avoids continuous oil contamination during transport, further improving both the degreasing efficiency and quality.
